Definitions

  • the strength of the electric field may increase as the dielectric constant of the diaphragm member decreases.
  • the liquid medium plasma discharge apparatus has the effects of being easy to fabricate, and of an electrode being resistant to corrosion, being cost-effective.
  • FIG. 4 is a view showing a variant of the microtube liquid medium plasma discharge apparatus.
  • the terminologies of the 1 st and/or the 2 nd can be used to explain many constituent elements, but the above constituent elements are not limited to the above terminologies.
  • the above terminologies can be named only for telling one constituent element from the other constituent elements.
  • the 1 st constituent element can be named as the 2 nd constituent elements without deviating from the range of the right according to the concept of the invention, and similarly, the 2 nd constituent element can be named as the 1 st constituent element.
  • the strength E of electric field at the microtude 31 of the dielectric diaphragm member 30 in the liquid medium can be obtained by the following equations.
  • E 1 is the strength of electric field at the microtube of the dielectric diaphragm member
  • E 2 is the strength of electric field in the liquid medium
  • d 1 is a length of the microtube of the dielectric diaphragm member
  • d 2 is a length of the liquid medium conductive volume
  • ⁇ 1 is the dielectric constant of the dielectric diaphragm member
  • ⁇ 2 is the dielectric constant of the liquid medium.
  • the microtube liquid medium plasma discharge apparatus is applicable to a variety of fields, including: environment-related fields such as drinkable water treatment, waste water treatment, sterilization of ballast water in a vessel, agricultural water treatment, substitution of agricultural chemicals, food processing, landscaping, sterilization of a water tank, sterilization of a humidifier, cleaning of medical instruments, cleaning water treatment, a desalination system, sterilization of a fish cage, sterilization of fishbowl, removal of red/green tide, or the like; industrial fields such as unit operation, wet processes for the manufacture of a semiconductor and a flat panel display, electrolytic plating, the manufacture of chemicals; the generation of underwater shockwaves; sonar equipment (the generation of underwater sound); underwater light source; underwater jet; or the like.
  • environment-related fields such as drinkable water treatment, waste water treatment, sterilization of ballast water in a vessel, agricultural water treatment, substitution of agricultural chemicals, food processing, landscaping, sterilization of a water tank, sterilization of a humidifier, cleaning of medical instruments, cleaning water treatment, a desalination
